IMPROVEMENT IN WARPlNG-MILLS.

Specification forming part of Letters Patent No. 132,959, dated November12, 1872.

To all whom it may concern:

Be it knownthatI, JOHNVV. FRIES, of Salem, in the county of Forsyth andState of North Carolina, have invented a new and Improved \Varping-Mill,of which the following is a specification:

Figure 1 is a top view, partly in section, of my improved warping-mill.Fig. 2 is a side elevation, partly in section, of the same.

Similar letters of reference indicate corresponding parts.

This invention has for its object to so arrange the heck of awarping-mill that the yarn wound upon the warp-cylinder will not becomeentangled while being'dyed or prepared after its removal from the mill.The invention consists in applying to the heck a vibratory motion,whereby the threads are laid diagonally, so that the threads of the samelayers will not be quite parallel and those of overlying thicknesseswill cross each other and not be parallel, thus preventing theirbecoming entangled.

In the accompanying drawing, the letter A represents the warp-cylinder,of suitable style and size. B is the heck, pivoted at a to a post orstandard, 0, of the warp machine. Through its apertures or slots theseveral threads of the yarn are drawn before they reach thewarp-cylinder. A slotted arm, 2, ex-

tends back from the heck B, and connects with a crank-pin, f, of a disk,9, which is rotated by a belt or band, h, from the cylinder A, orotherwise. The rotation of the disk g causes the heck to be oscillatedin the desired manner. The threads of each thickness or layer on thewarp-cylinder, being on the heck at unequal distances from the pivot onthereof, are laid on A at varying angles and not quite parallel to eachother. This is also advantageous, and prevents the threads from becomingentangled. The threads that cover each other on the cylinder will becrossed. The motion of each slot of the heck being increased with itsdistance from the pivot, the threads tend to increase in length thefurther they are from the heck-pivot; but the ordinary length of theheck makes no appreciable difference in the length of threads applied.

Having thus described my invention, I claim
